What makes the biggest difference in sound quality?

Room and Speakers obviously, however the Pre-Amp is the heart of your system which can really make or break it.

I have heard this from almost all hi-fi equipment dealers that speakers make the most of the difference, spend 75% on speakers etc.. Only one from Overture, DE said it is 50% speakers and 50% equipment that I agree.

75% Sound like a good number for a high end system.

However the leading question was aimed at preamps and amps (fuses, power cords, cables, etc.)

Most of the answers confirm with the premise of, “We hear what we want to hear.”

… what makes the bigger difference in sound quality on preamp‘s and power amps? Interconnects, speaker cables, power cords, or fuses?

What makes the biggest difference in sound quality is room treatment, followed by speakers and listening seat setup, followed by the gear itself.

People who sell speakers , sell speakers  .

The Room is it  . In big city I have found 400$ on up power cables  do help .

My observation exactly. Two components and only a list of four other items are in question.

You asked Ted … Quantum Purple’s, and this is after a complete heirloom of AQ’s bought just last year. Order of purchase sequence followed by a two month pause between each for evaluation / progress, if any. Speaker Cables, IC’s and PC’s.

For others it may have been a completely different set of questioning but for me it was quite clear.

A fuse, go figure
